1. Which number is lesser than 12,045

Correct Answer: Correct answer is: (B) 12,012.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question asks for a number that is lesser than 12,045. We need to compare each option to 12,045 to determine which one is smaller.

Common Mistakes: A common mistake would be to overlook the exact numerical comparison and choose an option that is not actually smaller than 12,045.

Explanations: To determine which number is lesser than 12,045, we compare each option: - 12,902 is greater than 12,045. - 12,012 is less than 12,045. - 12,085 is greater than 12,045. Thus, 12,012 is the only number that is lesser than 12,045.

Option Analysis:

Option A: 12,902 is greater than 12,045.
Option B: 12,012 is less than 12,045.
Option C: 12,085 is greater than 12,045.
Option D: None of the above is incorrect as 12,012 is a valid option.

2. Choose True (T) or False (F)678,357 is less than 678,573:

Correct Answer: Correct answer is: (A) True.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Very Easy

Concept notes: The question tests the ability to compare two numerical values.

Common Mistakes: A common mistake is to overlook the correct placement of digits when comparing numbers.

Explanations: To compare 678,357 and 678,573, we start from the leftmost digit and move right: 1. Both numbers have the same digits in the hundred-thousands, ten-thousands, and thousands place (678). 2. In the hundreds place, 678,357 has a 3 and 678,573 has a 5. 3. Since 3 is less than 5, 678,357 is less than 678,573.

Option Analysis:

Option A: Correct. 678,357 is indeed less than 678,573.
Option B: Incorrect. 678,357 is not greater than or equal to 678,573.
